Aircraft equipped with a singleINS/IRU, or a single GPS approved for primary means of navigation in oceanic and remoteareas, are eligible for RNP 10 authorization in a limited number of designated areas of operation.(The first area is the Gulf of Mexico oceanic CTAs.) With the exception of the requirement fortwo INSs or IRUs, the guidance in Order 8400.12, subparagraph 13b(1) applies. INS and IRUsystems must be approved in accordance with part 121 appendix G. With the exception of therequirement for two primary means GPSs, the guidance in Order 8400.12, subparagraph 13b(3)applies.

Unless theoperator takes action to extend the approved navigation system time limit and/or plans to updatethe system en route, a baseline RNP 10 time limit of 6.2 hours, starting at the time the systemwas placed in navigation mode, is applicable. See Order 8400.12, subparagraph 13d onextending navigation system time limit, and Order 8400.12, subparagraph 13e on en routeupdating.i) Order 8400.12, subparagraph 13c specifies that for navigation systems notapproved under existing criteria, the operator may demonstrate RNP 10 eligibility through datacollection in accordance with Order 8400.12, subparagraph 13c using the processes detailed inOrder 8400.12, appendix A or E.j) Order 8400.12, subparagraph 16f requires the operator to show the routes orareas where it is eligible to operate if restrictions (e.g., INS RNP 10 time limit) apply tonavigation systems. In accordance with Order 8400.12, subparagraph 16f, the operator canconduct a one-time evaluation of eligibility to fly in an RNP 10 area of operation or on specificRNP 10 routes, or may elect to evaluate on a per-flight basis.1. For a one-time evaluation of a specific RNP 10 area or track system,aviation safety inspectors (ASI) should expect the operator to accomplish the following:21UNCONTROLLED COPY WHEN DOWNLOADEDCheck with FSIMS to verify current version before using
